PROBLEM TO BE SOLVED: To provide a method of manufacturing a part for a stator, by which punching burr protruding on front and rear sides is not generated on an end of an elongated conductor plate, and interlayer short circuit hardly occurs even in an insulating distance in lamination is long depending on the circumstances. SOLUTION: The method of manufacturing a part for a stator which is used as a portion of a coil material wound around a stator magnetic pole and includes a conductive coil material 17 having an elongated conductor plate and an insulating sheet pasted on its front surface, has a first step of preparing a wide conductor plate material 12 having an insulating sheet 10 pasted on its one surface and having a width enough to punch the conductive coil material 17; a second step of executing half-blanking processing of the conductive coil material 17 from the front surface for the wide conductor plate member 12; and a third step of pushing the half-blanked conductive coil material 17 back into the wide conductor plate member 12 from the rear side, wherein the occurrence of burr on the front and rear sides is prevented on the end of the elongate conductor plate forming the conductive coil material 17.
